Even Kate Upton Isn't Always Confident Wearing a Bathing Suit

Kate Upton may have countless magazine covers—in bikinis, no less— movie credits, and runway shows on her resumé, but that doesn't mean she's always feelin' herself. As it turns out, when it comes to loving her body, she has difficult days just like the rest of us.

“I’m still not confident in a bathing suit!” Upton told Yahoo Style in a recent interview. “That’s why you eat healthy and work out, to feel your best. You always have struggles. It’s not like I always feel my best. Everybody has moments where they don’t feel confident in a bikini. It’s what we’re striving for: self-love. We work our way up. When I don’t feel my best, that’s OK.”

Starting her career as a model, Upton says she faced constant scrutiny in relation to her body. “Honestly, because coming from the fashion world, weight—when I first started modeling—was very important," she says. "How much you weighed, how much you needed to lose, whatever it was." It was "insinuated, always" that she needed to lose weight, and these days she isn't having any of it.

“I’m not trying to be fit for a number on a scale," she says. "Whenever I’m happiest, I try to maintain that. I don’t need a number.” According to Yahoo Style, the The Other Woman star has never owned a scale and, instead, sticks to a balanced lifestyle as a means of feeling good about herself and her body.

"I try to eat healthy and work out and keep up a healthy lifestyle," she says, touting weight-training-based workouts that help raise her metabolism and give her the ability to enjoy food. "But if I want a treat, I allow myself that freedom."

Upton, who is planning her nuptials to Detroit Tigers pitcher Justin Verlander, also has no intention of shedding for the wedding. According to People, she'll be steering clear of any crazy bridal diets. “I never get on a scale because you can’t judge yourself for how much you weigh,” she says. “What really matters is how good I feel.”

Upton's honesty is proof that even the most seemingly confident people don't feel 100 percent amazing, 100 percent of the time—no matter how fabulous they look posing topless on the cover of three separate Sports Illustrated swimsuit issues
